it's hot, let's switch off

yup, it's been a really hot month -mostly- we've had birds tweeting at night, early blooms and sprouting bulbs, so why are we still keeping heaters on, opening windows and walking around in T-shirts at home? I'm not complaining, but Christian Aid is claiming that if we all turned our thermostats down by one degree, it would help us combat drought in Africa (www.climatechanged.org ). Seems a little ambitious, but it does make my parents -whose central heating has broken down for now 2 years- seem like saints. Bless them...
